 4.9 No later than five Dealing Days prior to the EGM Date, the Company shall give Nomura an
undated letter from the Company to CRESTCo confirming that each condition to enable the Nil Paid Rights and the Fully Paid Rights to be admitted as a Participating Security in CREST has been satisfied. Immediately after Admission, Nomura shall date
the letter and deliver it to CRESTCo. 
  









 4.10 Each document referred to in this Clause 4 and in Schedule 1 and any Supplementary Prospectus shall be in the form
reasonably satisfactory to Nomura. 
  

	5.	ALLOTMENT 

  
 5.1 Subject to: 
  

	(a)	the UK Listing Authority having granted permission for the New Shares (nil paid) to be admitted to the Official List and the London Stock Exchange having granted permission for the
New Shares (nil paid) to be admitted to trading on its market for listed securities and the admission of the Nil Paid Rights and the Fully Paid Rights as a Participating Security in CREST (subject only to the allotment of the New Shares); and


  

	(b)	the passing of the Resolution in accordance with Clause 2.1(d), 

  
 the Company shall provisionally allot the New Shares (nil paid) on the EGM Date to Qualifying Holders on the basis referred to in Recital (A) pursuant to a resolution of
the Board. The allotment of the New Shares shall be made upon the terms and subject to the conditions set out in the Circular and to be set out in the Provisional Allotment Letter and on the basis referred to in Clause 5.4 for acceptance and payment
in full by not later than 9.30 a.m. on the Acceptance Date. Fractions of New Shares shall not be allotted to Qualifying Holders. 
  
 5.2 The Company may only exercise its right in paragraph 4(h) of Part 3 of the Circular in relation to Qualifying CREST Holders to allot and issue the Nil Paid Rights,
the Fully Paid Rights or the New Shares in certificated form if it has first obtained Nomura’s written consent (such consent not to be unreasonably withheld or delayed). 
  
 5.3 By not later than the third Dealing Day after the Acceptance Date, the Company will confirm the provisional allotments of the New Shares
which have been taken up and cancel the provisional allotments of the New Shares which have not been taken up and will allot a number of New Shares equal to the number of New Shares for which provisional allotments were not taken up in favour of the
persons who, pursuant to Clauses 6.6 and/or 7, are to subscribe for such New Shares, in each case pursuant to a resolution of the Board. 
  
 5.4 The New Shares, when issued and fully paid, will rank pari passu in all respects with the existing issued Ordinary Shares and will be free from all liens, charges,
encumbrances and equities. 
  

	6.	NEW SHARES NOT TAKEN UP 

  
 6.1 The Company confirms that it has requested the Depositary to appoint Nomura to endeavour
to sell the New Shares (in nil paid form) to be provisionally allotted to the Depositary or its agent under the Rights Issue and to account for any sale proceeds to ADS holders in accordance with the terms of the Deposit Agreement. To the extent
that purchasers for such New Shares are not procured, such New Shares will be dealt with as New Shares not taken up in accordance with Clause 6.6. 
  









 6.2 By not later than 5.00 p.m. on the second Dealing Day prior to the Acceptance Date, the Company will (or will procure
that the Receiving Agent will) notify Nomura in writing of the number of New Shares which represents the aggregate of fractional entitlements arising in respect of the Rights Issue and of the number of New Shares attributable to Overseas Holders
under the Rights Issue (other, for avoidance of doubt, than any Ordinary Shareholders with registered addresses in the United States, Canada, Australia, Japan or the Republic of Ireland to whom an offer of New Shares is made pursuant to any
exemption which the Company and Nomura agree is available from applicable overseas securities laws). Such New Shares will be dealt with as New Shares not taken up in accordance with Clause 6.6 and the Company will procure that the Receiving Agent
pays to Overseas Holders pro rata to their holdings of Ordinary Shares as at 5.00 p.m. on the Record Date the net proceeds received by the Receiving Agent in respect of the sale of rights to New Shares attributable to them as soon as practicable
after receipt (save that individual amounts of less than £3.00 will not be so paid but will be paid to the Company for its own benefit). The net proceeds received by the Receiving Agent in respect of the sale of fractional entitlements to New
Shares shall be paid to the Company for its own benefit. 
  
 6.3 If, by 9.30 a.m.
on the Acceptance Date, all the New Shares shall have been taken up, or are subsequently deemed to have been taken up pursuant to Schedule 2, Nomura’s obligations under Clauses 6 and 7 shall cease. 
  
 6.4 Whether or not any New Share shall have been taken up shall be determined in accordance
with the provisions of Schedule 2 and the parties agree to give effect to the provisions of Schedule 2. 
  
 6.5 As soon as practicable after 9.30 a.m. on the Acceptance Date and by not later than 2.30 p.m. on the Acceptance Date, the Company will (or will procure that the Receiving Agent will) notify Nomura in writing of
the number of New Shares which have not been taken up. 
  
 6.6 Nomura will
endeavour to procure subscriber(s) for New Shares equivalent to the number of New Shares which are not taken up (or, at its discretion, for as many as can be so procured) upon the terms (in so far as the same are applicable) of the Circular and the
Provisional Allotment Letter as soon as reasonably practicable and in any event by not later than close of business on the second Dealing Day after the Acceptance Date if an amount which is not less than the total of the Subscription Price
multiplied by the number of such New Shares for which subscriber(s) are so procured and the expenses of procurement (including any applicable brokerage and commissions and amounts in respect of value added tax which are not recoverable) can be
obtained. Any subscribers so procured by Nomura shall subscribe for the New Shares at the Subscription Price and any amount in excess of the Subscription Price shall be paid by the subscriber and received by Nomura on the basis that the same shall
be applied in meeting the expenses of procuring such subscription (including any applicable brokerage and commissions and amounts in respect of value added tax which are not recoverable) and that any balance remaining shall be payable to
non-accepting Qualifying Holders and Overseas Holders in accordance with Clauses 6.8 and 6.2 Nomura shall not be obliged to endeavour to procure such subscriber(s) and may, at any time on or after the Acceptance Date, cease to endeavour to procure
any 

  









 
such subscriber(s) if, in its opinion, it is unlikely that any such subscriber(s) can be so procured by such time on the terms referred to above whereupon
Nomura shall not be under any obligation to endeavour to procure any such subscriber(s). 
  
 6.7 Nomura shall: 
  

	(a)	by not later than the third Dealing Day after the Acceptance Date inform the Company of the number of New Shares to be issued in each of certificated form and uncertificated form to
subscribers procured pursuant to Clause 6.6; and 

  

	(b)	in respect of the amounts received by it in accordance with Clause 6.6 (and after deduction of the expenses of procuring subscribers, including amounts in respect of value added tax
which are not recoverable), by not later than the sixth Dealing Day after the Acceptance Date procure payment to: 

  

	 	(i)	the Company (or to the Receiving Agent on its behalf) of the Subscription Price in respect of the New Shares for which subscribers are procured pursuant to Clause 6.6; and


  

	 	(ii)	to the Receiving Agent (on behalf of the persons, and in the proportions, referred to in Clause 6.8) of the balance, 

  
 against the issue of New Shares in certificated form in such names and
denominations as specified by Nomura pursuant to paragraph (a) above in respect of the New Shares to be issued in certificated form and subject to CRESTCo crediting Nomura’s stock account in CREST (notified by Nomura) with the number of New
Shares specified by Nomura pursuant to paragraph (a) above in respect of the New Shares to be issued in uncertificated form. 
  
 6.8 The Company shall procure that the Receiving Agent makes payment of the amount received by the Receiving Agent pursuant to Clause 6.7(b)(ii) to the non-accepting
Qualifying Holders to whom New Shares were provisionally allotted pro rata to their lapsed provisional entitlements as soon as practicable after receipt (save that individual amounts of less than £3.00 will not be so paid but will be paid to
the Company for its own benefit). If the Nil Paid Rights were in certificated form when they lapsed, such payment shall be made to the person whose name and address appears on page one of the Provisional Allotment Letter relating to those Nil Paid
Rights. If the Nil Paid Rights were in uncertificated form when they lapsed, such payment shall be made to the person registered as the holder of those Nil Paid Rights when they were disabled in CREST. 
  
 6.9 In the absence of any fraud or wilful default by Nomura, Nomura shall not be responsible,
whether to the Company, any Qualifying Holder, any other shareholder or otherwise, for any loss or damage to any person arising from any such transactions as are mentioned in this Clause 6 or for any insufficiency or alleged insufficiency of any
dealing price at which subscribers for New Shares may be procured by it or for the timing of any such subscription or for any determination by Nomura to cease to endeavour to procure such subscribers. 
  










	7.	UNDERWRITING 

  
 7.1 Nomura shall procure subscribers or, to the extent such subscribers are not procured, itself subscribe on the terms and subject to the conditions and on the basis of
the information contained in the Circular and the Provisional Allotment Letter (other than as to the time and method of acceptance and payment) for any of the New Shares not taken up and for which subscribers are not procured pursuant to Clause 6.6.

  
 7.2 Nomura shall procure payment of the Subscription Price for such number of
New Shares as it is required to subscribe and/or procure subscribers for pursuant to Clause 7.1 to the Company (or to the Receiving Agent) by not later than the sixth Dealing Day after the Acceptance Date against the issue of New Shares in
certificated form in such names and denominations as Nomura may require in respect of the New Shares to be issued in certificated form and subject to CRESTCo crediting Nomura’s stock account in CREST (notified by Nomura) with the number of New
Shares specified by Nomura in respect of such New Shares to be issued in uncertificated form. 
  

	8.	COMMISSIONS AND EXPENSES 

  

8.1 Subject to the Press Announcement being published, the Company shall pay Nomura in consideration for its services under this Agreement: 
  

	(a)	a commitment commission of  1/2 per cent.
(one half of one per cent.) of the value at the Subscription Price of the aggregate number of the Underwritten Shares (the Gross Proceeds); and 

  

	(b)	a commission of  1/8 per cent, (one eighth of
one per cent.) of the Gross Proceeds for each period of seven days (or part of seven days) after the first thirty days of Nomura’s commitment from and including the date of this Agreement to (and including) the second Dealing Day after the
Acceptance Date or, if earlier, the date on which Nomura’s obligations under this Agreement cease in accordance with Clause 2.3 or Clause 12. 

  
 Such commissions shall be payable together with any applicable value added tax. 
  
 8.2 If Nomura’s obligations under Clauses 6 and 7 of this Agreement become unconditional
in all respects and this Agreement is not terminated in accordance with its terms prior to Admission, the Company shall pay Nomura in consideration for its services under this Agreement: 
  

	(a)	a further commission of  1/2 per cent. (one
half of one per cent.) of the Gross Proceeds; 

  

	(b)	a further commission of 3 per cent. of the Gross Proceeds; and 

  

	(c)	a documentation and corporate advisory fee of £150,000; 

  









 Such fee and commissions shall be payable together with any applicable value added tax. 
  
 8.3 If Nomura’s obligations under Clauses 6 and 7 of this Agreement do not become
unconditional in all respects or this Agreement is terminated in accordance with its terms prior to Admission, the Company shall pay Nomura a termination fee of £70,000 in consideration of its services under this Agreement together with any
applicable value added tax. 
  
 8.4 Subject to the Press Announcement being
published, the Company shall pay the commissions set out in Clause 8.1 whether or not the Circular, the Form of Proxy and the Provisional Allotment Letters are despatched, whether or not Admission occurs and whether or not the obligations of Nomura
under this Agreement become unconditional or this Agreement is terminated in accordance with its terms. 
  
 8.5 The Company shall pay the fee and commissions payable to Nomura by not later than 3.00 p.m. on the day upon which Nomura procures payment to the Company (or to the Receiving Agent) pursuant to Clauses 6 or 7 or,
if earlier, on the first Dealing Day after the date on which Nomura’s obligations under this Agreement cease in accordance with Clause 2.3, Clause 6.1 or Clause 12. Without prejudice to its right to receive payment directly from the Company
pursuant to this Clause 8.5, Nomura shall be entitled and is authorised to deduct some or all of such fee and commissions and any fee and expense which the Company has agreed to pay Nomura from any amount otherwise payable by Nomura to the Company
under this Agreement. 
  
 8.6 Out of the commissions referred to in Clause 8.1,
Nomura shall pay any sub-underwriting commissions payable to such persons (if any) as it may procure to subscribe New Shares. 
  
 8.7 In addition to the fees and commissions referred to in Clauses 8.1, 8.2 and 8.3 the Company shall pay (whether or not Nomura’s obligations under this Agreement
become unconditional) all costs and expenses of, or in connection with, the Rights Issue, the EGM, the allotment and issue of the New Shares and this Agreement. This shall include (but shall not be limited to) the UK Listing Authority and the London
Stock Exchange listing and trading fees, other regulatory fees and expenses, printing and advertising costs, postage, the Receiving Agent’s charges, its own and Nomura’s legal and other out-of-pocket expenses reasonably and properly
incurred, all accountancy and other professional fees, public relations fees and expenses and all stamp duty and stamp duty reserve tax (if any) and other duties and taxes other than corporation tax incurred by Nomura on its income, profits or gains
in connection with the Rights Issue, the EGM, the allotment and issue of the New Shares and this Agreement provided that the Company shall not be liable for any such stamp duty or stamp duty reserve tax as may arise pursuant to Sections 67, 70, 93
and 96 of the Finance Act 1986, and nor shall it be liable for any stamp duty or stamp duty reserve tax arising as a result of any sales of the New Shares by Nomura or any subscriber for New Shares. The Company shall immediately on request pay or
reimburse Nomura the amount of any expenses which are to be borne by the Company and which Nomura (or any subscriber for New Shares) has paid. 
  









 8.8 Where, pursuant to this Agreement, a sum (a Relevant Sum) is paid or reimbursed to Nomura
in respect of any cost or expense and that cost or expense includes an amount in respect of value added tax (the VAT Element), the Company shall also pay to Nomura in respect of value added tax: 
  

	(a)	if the Relevant Sum constitutes for value added tax purposes payment or reimbursement to Nomura of the consideration for the supply of goods or services made to Nomura (including
where Nomura acts as agent for the payer of the Relevant Sum (the Payer) within the meaning of Section 47(3) of the Value Added Tax Act 1994), a sum equal to the proportion of the VAT Element that Nomura certifies as
representing irrecoverable input tax in the hands of Nomura, that certificate to be conclusive save in the case of manifest error; and 

  

	(b)	if the Relevant Sum constitutes for value added tax purposes the reimbursement of a cost or expense incurred by Nomura as agent for the payer (excluding when Nomura acts as agent
for the Payer within the meaning of Section 47(3) of the Value Added Tax Act 1994), a sum equal to the whole of the VAT Element, 

  
 and where a sum equal to the VAT Element has been reimbursed to Nomura under sub-clause 8.8(b) above, Nomura shall provide the Payer with an appropriate tax invoice in
respect of the supply to which the Relevant Sum relates, that is to say a tax invoice naming the Payer as a recipient of supply and issued by the person making the supply. 
  
 8.9 Unless otherwise expressly provided, any amount to be paid in respect of any services to be supplied pursuant to this Agreement shall
not include any amount in respect of value added tax and if such value added tax is applicable to a supply of any such services, an amount equal to such value added tax should be added to the amount in question (or any increase to that amount) and
shall be paid by the recipient of that supply to the supplier. The supplier shall issue to the recipient of the supply a proper value added tax invoice in respect thereof. In the event that the recipient of the supply has paid an amount in respect
of value added tax to the supplier in respect of a supply of services and an adjustment is made to that amount pursuant to any provision of this Agreement with the effect that the supplier has to make a payment to the recipient of the supply, the
supplier shall in addition to the payment of such amount, refund to the recipient of the supply an amount in respect of value added tax on such payment as is required by applicable law. 
  

	9.	RESTRICTIONS ON ACTIONS AND ANNOUNCEMENTS 

  
 9.1 Without Nomura’s prior consent (such consent not to be unreasonably withheld or
delayed), the Company undertakes that it will not (and the Company will use all reasonable endeavours to procure that no member of the Group will) at any time prior to the date which is ten Dealing Days after, as appropriate, the Acceptance Date or
the date that Nomura’s obligations under this Agreement cease in accordance with Clause 2.3: 
  

	(a)	allot, issue or grant any rights in respect of any securities of the Company (except for the grant of options under, and the allotment and issue of Ordinary Shares pursuant to
options granted under, the Company’s existing share option schemes, in each case in accordance with normal practice); or 

  










	(b)	circulate, distribute, publish, issue or make (nor authorise any other person to circulate, distribute, publish, issue or make) any press or public announcement or advertisement,
statement or communication (other than an announcement, advertisement, statement or communication required by law or any regulatory body and save in respect of any announcement, advertisement, statement or communication in connection with any matter
arising in the ordinary course of business of the Group that is not material in the context of the Rights Issue, but subject always to Clause 9.2), either individually or jointly with any other person, in relation to the Company, the Group,
Admission, or the Rights Issue or otherwise relating to the assets, liabilities, profits, losses, financial or trading condition or prospects of the Company or the Group and whether in response to enquiries or otherwise. 

  
 9.2 The Company undertakes that it will not at any time during the period ending on the date
that is ten Dealing Days following the Acceptance Date make any public announcement, advertisement, statement or communication as is referred to in Clause 9.1 or relating to any matters, events or circumstances which may be necessary to be made
known to the public in order to enable the shareholders of the Company and the public to appraise the position of the Company or to avoid the establishment of a false market in its securities, either individually or jointly with any other person
(including, without limitation, any matter whatsoever which would require notification by the Company to a Regulatory Information Service in accordance with the provisions of the Listing Rules), without first, where reasonably practicable: (a)
notifying Nomura as to the content, form and manner of publication of such announcement, advertisement, statement or communication; (b) making available drafts of any such announcement, advertisement, statement or communication to Nomura in
sufficient time prior to its publication to allow Nomura an opportunity to consider and comment on the same; and (c) consulting with Nomura as to the content, form and manner of publication of such announcement, advertisement, statement or
communication. 
  
 9.3 The Company undertakes to make all such announcements
concerning the Rights Issue as shall be necessary to comply with the Listing Rules, the Admission and Disclosure Standards and section 118 and section 397 of the FSMA or which Nomura otherwise reasonably considers to be necessary or desirable
(including, without limitation, for the purposes of procuring any sub-underwriters or potential subscribers for any New Shares in accordance with this Agreement) and Nomura shall be entitled to make any such announcement if the Company fails (in the
opinion of Nomura acting in good faith) promptly to fulfil its obligations under this Clause 9.3. 
  

	10.	REPRESENTATIONS, WARRANTIES AND UNDERTAKINGS 

  
 10.1 The Company represents, warrants and undertakes to Nomura in the terms set out in
Schedule 3. The Company acknowledges that Nomura is entering into this 

  









 
Agreement in reliance on such representations, warranties and undertakings. Each representation, warranty and undertaking shall be construed separately and
shall not be limited or restricted by reference to or inference from the terms of any other representation, warranty and undertaking or any other term of this Agreement. 
  
 10.2 The Company shall not cause or permit (and shall procure that no other member of the Group nor any of its or their respective
directors, officers, employees or agents shall cause or (so far as they are able using their reasonable endeavours) permit) any event to occur or omit to do anything between the date of this Agreement and the date which is ten Dealing Days after, as
appropriate, the Acceptance Date or the date on which Nomura’s obligations under this Agreement cease in accordance with Clause 2.3 and/or Clause 12.1 which would make any statement in paragraph 2 of Schedule 3 untrue, inaccurate or misleading
and/or any other statement in Schedule 3 materially untrue, inaccurate or misleading if, in such case, such statement were repeated at such date by reference to the facts and circumstances then existing. 
  
 10.3 The Company shall promptly notify Nomura (giving reasonable details) if it comes to the
knowledge of the Company or any Director that any statement in Schedule 3 was breached or untrue, inaccurate or misleading at the date of this Agreement or would be breached or untrue, inaccurate or misleading if repeated by reference to the facts
and circumstances existing at any time during the period referred to in Clause 10.2 or if the Company is in breach of any of its obligations under this Agreement. 
  
 10.4 The Company agrees that Nomura and any sub-underwriter who acquires New Shares shall be entitled to the same remedies and rights of
action against the Company, and to the same extent, as any person who acquires any New Shares pursuant to the Rights Issue on the basis of the Circular and the Provisional Allotment Letter. 
  
 10.5 References in this Agreement to a representation, warranty or undertaking being (or not
being) true and accurate or not being (or being) misleading “in any material respect” shall mean material in the context of the Rights Issue and/or the underwriting of the New Shares. In that connection and otherwise in this
Agreement in relation to references to a matter which would or might be “material in the context of the Rights Issue” and/or “material in the context of Admission” and/or “material in the
context of the underwriting of the New Shares”, a matter shall, without limitation, be deemed to be so material if it would have been material for disclosure to potential sub-underwriters or other subscribers for New Shares had such
matter existed when such sub-underwriters or other subscribers for New Shares were sought for the New Shares. 
  
 10.6 The representations, warranties and undertakings referred to in Clauses 10.1 to 11.4 shall remain in full force and effect notwithstanding completion of all matters and arrangements referred to in, or
contemplated by, this Agreement. 
  
 10.7 Where any of the representations,
warranties and undertakings are qualified by reference to awareness and/or knowledge and/or information and/or belief, that reference shall be deemed to include a statement to the effect that it has been given after making such enquiries (if any)
within the Group as were reasonable. 
  









 10.8 Each of the representations, warranties and undertakings shall be qualified to the extent of any facts or
information fairly disclosed in the Circular. 
  
 10.9 The Company and Nomura each
undertake to observe and comply with the provisions in respect of overseas shareholders set out in Part 3 of the Circular under the heading “Overseas Shareholders”. 
  

	11.	INDEMNITY 

  
 11.1 No claim shall be made by the Company or any of its subsidiary undertakings or the Directors against Nomura, any holding company of Nomura, any subsidiary
undertaking of Nomura or of any such holding company or any of the directors, officers, agents or employees of any such person (each of the foregoing, an Indemnified Person) to recover any loss, damage, cost, charge or expense that the
Company, any of its subsidiary undertakings or any of their respective directors, officers, agents or employees or any subscriber for or purchaser of New Shares pursuant to the Rights Issue or the arrangements contemplated by the Circular or this
Agreement or any subsequent purchaser or transferee of any New Shares may suffer or incur and which arises out of the carrying out by any Indemnified Person of obligations or services in connection with this Agreement or otherwise in connection with
the Rights Issue, Admission or the arrangements contemplated by the Circular, except, in each case, to the extent only that the loss, damage, cost, charge or expense is agreed or is finally determined to have arisen (otherwise than as a result of a
payment made or an obligation or liability to make payment arising under Clause 11.2) from any negligence or wilful default of the relevant Indemnified Person, or breach of the rules made under the FSMA by the Financial Services Authority by such
person. 
  
 11.2 The Company undertakes to indemnify on an after-tax basis each
Indemnified Person against all or any claims (whether or not successful, compromised or settled), actions, liabilities, demands, proceedings or judgments (each a Claim) asserted or established against that Indemnified Person in any
jurisdiction by any subscriber for or purchaser of New Shares pursuant to the Rights Issue or the arrangements contemplated by the Circular or this Agreement or by any subsequent purchaser or transferee of any New Shares or any governmental agency
or regulatory body or any other person whatsoever and against all losses, costs, charges or expenses (including legal fees) and Taxes (other than corporation tax, value added tax, stamp duty or stamp duty reserve tax incurred by the Indemnified
Person on its income, profits or gains) (each an Expense) (including, but not limited to, all Expenses reasonably suffered or incurred in disputing any Claim and/or in establishing a right to be indemnified on an after-tax basis
pursuant to this Clause 11.2 and/or in seeking advice regarding any Claim or in any way related to or in connection with this indemnity) which that Indemnified Person may suffer or incur if the Claim or Expense arises, directly or indirectly, out of
or is connected with anything done or omitted to be done by any person (including that Indemnified Person) in connection with the Rights Issue, Admission or the arrangements contemplated by the Circular or this Agreement, including but not limited
to: 
  

	 	(i)	the Circular not containing or fairly presenting, or being alleged not to contain or not to fairly present, all information required to be contained therein or any statement therein
being or being alleged to be in any material respect untrue, inaccurate, incomplete, misleading or not based on reasonable grounds; and/or 

  










	 	(ii)	the distribution, issue or approval of the Circular or other documents or materials in connection with the Rights Issue (including the issue or approval for the purpose of Section
21 of the FSMA of any financial promotion); and/or 

  

	 	(iii)	any breach or alleged breach by the Company of any of its obligations in this Agreement or any other agreement to be entered into by it in connection with the Rights Issue or the
arrangements contemplated by the Circular or this Agreement; and/or 

  

	 	(iv)	any failure or alleged failure by the Company, any of the Directors or any of its or his agents, employees or advisers to comply with the FSMA or the Listing Rules or any other
legal or regulatory requirements in any jurisdiction in relation to the Rights Issue, Admission or the arrangements contemplated by the Circular or this Agreement, 

  
 provided that: 
  

	(a)	an Indemnified Person shall not be entitled to any indemnity from the Company under this Clause 11.2 in relation to any Claim or Expense to the extent only that the Claim or Expense
is in respect of an unrealised or realised loss on any New Shares that the Indemnified Person acquires pursuant to this Agreement or any expenses of sale of such New Shares unless (but only to the extent that) such Claim or Expense results from,
directly or indirectly, the neglect or default of the Company or any breach by the Company of any of its obligations under this Agreement; 

  

	(b)	an Indemnified Person shall not be entitled to any indemnity under this Clause 11.2 in relation to any Claim or Expense to the extent only that the Claim or Expense concerned is
agreed or is finally determined to have arisen from the negligence or wilful default of the Indemnified Person, or breach of the rules made under the FSMA by the Financial Services Authority by such person; and 

  

	(c)	an Indemnified Person shall not be entitled to recover from the Company under this Clause 11.2 in relation to any Claim or Expense to the extent that such indemnification is not
permissible under Part V, Chapter VI of the Companies Act. 

  
 11.3
Subject to any requirement of a relevant insurer, each Indemnified Person to whom Clause 11.2 applies will promptly notify the Company in writing if it becomes aware of any Claim which may give rise to a liability under Clause 11.2, will keep the


  









 
Company informed of the progress of any Claim and will consult with the Company with respect to the handling of any Claim. 
  
 11.4 The Company will (provided it is aware of the same, after due and careful enquiry)
promptly notify Nomura of any limitation (whenever arising) on the extent to which the Company and/or any of its subsidiary undertakings may claim against any third party or parties and/or of any waiver or release of any right of the Company or any
of its subsidiary undertakings to so claim (each a Limitation) in respect of anything which may arise, directly or indirectly, out of or is based upon or is in connection with the Rights Issue or the subject matter of the obligations
or services to be performed under this Agreement or in connection with the Rights Issue by Nomura or on its behalf. Where any damage or loss is suffered by the Company for which any Indemnified Person would otherwise be jointly and severally liable
with any third party or third parties to the Company or any of its subsidiary undertakings, the extent to which such loss will be recoverable from the Indemnified Person shall be limited so as to be in proportion to the contribution of the
Indemnified Person to the overall fault for such damage or loss, as agreed between the parties, or, in the absence of agreement, as finally determined by a court of competent jurisdiction but, in any event, the Indemnified Person shall have no
greater liability than if the Limitation did not apply. 
  
 11.5 The degree to
which any Indemnified Person shall be entitled to rely on the work of any adviser to the Company or any other third party will be unaffected by any Limitation (as defined in Clause 11.4) which the Company or any of its subsidiary undertakings or
associates or any Director may have agreed with the third party. 
  
 11.6 Insofar
as the Company has engaged any adviser (a capped adviser) on the basis that its liability to the Company arising out of any default by it or otherwise in connection with the Rights Issue is subject to any limitation, exclusion or
restriction of liability, the liability of each Indemnified Person to the Company or any other person in respect of any default by that Indemnified Person under this Agreement or otherwise in connection with the Rights Issue shall not exceed the
amount for which that Indemnified Person would have been liable after deducting any additional amount which that Indemnified Person would have been entitled to recover from the capped adviser, in the absence of the limitation, exclusion or
restriction of the capped adviser’s liability, by way of contribution to that Indemnified Person, in respect of the matter concerned. 
  
 11.7 All sums payable to Nomura or any other Indemnified Person pursuant to this Clause 11 shall be paid within 30 days of written demand by Nomura. 
  

	12.	TERMINATION 

  
 12.1 If at any time before Admission: 
  

	(a)	there has been a breach by the Company of any of its obligations under this Agreement, which Nomura, acting reasonably, considers to be material in the context of the Rights Issue
or Admission; or 

  










	(b)	any matter or circumstance arises or pertains as a result of which either of the Conditions set out in sub-clauses (b), (g) or (h) in Clause 2.1 will not be satisfied at the
required time(s) (if any) and continue to be satisfied as at Admission; or 

  

	(c)	it shall come to the notice of Nomura that any statement contained in the Circular is or has become untrue, incorrect or misleading in any respect, or any matter has arisen, which
would, if the Rights Issue was made at that time, constitute a material omission from the Circular and which, in any such case, Nomura considers to be material and adverse in the context of the Rights Issue or Admission; or 


 

	(d)	any of the representations, warranties and undertakings contained, or referred to, in this Agreement is not, or has ceased to be, true and accurate in all material respects by
reference to the facts and circumstances subsisting at that time; or 

  

	(e)	in the reasonable opinion of Nomura, acting in good faith, there shall have been a significant adverse change in or any development (including any development relating to the
Group’s products or drug candidates or any product or drug candidate reasonably likely to be a competitor of any of the Group’s products or drug candidates but not including any development relating to the pharmaceutical or biotechnology
industry generally) involving a significant prospective adverse change in or affecting the condition (financial or otherwise), prospects, earnings, business affairs, properties, results of the Group as a whole whether or not arising in the ordinary
course of business, as a result of which Nomura, acting in good faith, considers it to be impracticable, inappropriate or inadvisable to proceed with the Rights Issue or Admission; or 

  

	(f)	in the reasonable opinion of Nomura there shall have been such a change in national or international financial, political or economic conditions or any material changes in currency
exchange rates or exchange controls or a declaration of a general moratorium on commercial banking activities in the United Kingdom or New York by any United Kingdom, New York State or United States federal authorities or any outbreak or escalation
of hostilities (including any such change or event which causes a change in financial markets or any calamity or crisis or any disruption to trading generally or trading of any securities of the Company on any stock exchange) which, in any such
case, Nomura considers would be likely to materially prejudice the success of the Rights Issue and the distribution of the New Shares, 

  
 Nomura may, in its absolute discretion, by notice in writing given to the Company, terminate this Agreement, in each case except to the extent specified in Clause 12.3.

  
 12.2 Nomura shall have no right to terminate this Agreement before Admission
except as provided in Clause 12.1 or Clause 2.3. Nomura shall have no right at all to terminate this Agreement on or after Admission. 
  









 12.3 The termination of this Agreement (save to the extent specified in this Clause 12.3) pursuant to Clauses 2.3 or 12.1
shall be without prejudice to: 
  

	(a)	any claim in respect of a breach of this Agreement prior to the termination; 

  

	(b)	any obligation of the Company in respect of New Shares which have already been issued, subscribed and paid for at the time of such termination (in which case this Agreement shall
continue to apply to such New Shares and, in particular, Clauses 1, 8, 9,10,11, this Clause 12.3, Clauses 13, 14 and Clauses 16 to 22 inclusive will continue to apply and Nomura shall be entitled to the fees and commissions pursuant to Clause 8);
and 

  

	(c)	the provisions of Clauses 1, 8, 9, 10, 11, this Clause 12.3, Clauses 13, 14 and Clauses 16 to 22 inclusive which will continue to apply except that Nomura shall not be entitled to
receive the fee and commissions referred to in Clause 8.2. 

  

	13.	WITHHOLDING 

  
 All sums payable by the Company to Nomura or any other Indemnified Person (for the purposes of this Clause 13 only, each a
payee) under this Agreement shall be paid in pounds sterling free and clear of all deductions or withholdings unless the deduction or withholding is required by law, in which event, save to the
extent that the payee is compensated for the relevant deduction or withholding by virtue of the fact that the payment it receives is made on an after-tax basis, the relevant person shall pay such additional amount as shall be required to ensure that
the net amount received by the payee will equal the full amount which it would have been entitled to receive had no such deduction or withholding been required to be made. 
  

	14.	MISCELLANEOUS 

  
 14.1 For the avoidance of doubt, the Company acknowledges and agrees that it is responsible for any due diligence carried out in relation to the Rights Issue and that
neither Nomura nor any of its advisers shall be responsible to the Company or any Director for any due diligence in relation thereto or for verifying the accuracy or fairness of any information published by or on behalf of the Company in connection
with the Rights Issue unless it or they have agreed in writing to take specific responsibility for such due diligence or verification. 
  
 14.2 The Company agrees that for the purpose of the Rights Issue (including for the purposes of seeking to procure any sub-underwriters for the New Shares) Nomura shall
not be responsible for the provision of or obtaining advice as to the requirements of applicable laws or regulations of any jurisdictions other than the United Kingdom nor shall it be responsible where it or the Company has acted in the absence of
such advice or in reliance on any advice obtained by the Company in respect thereof. 
  
 14.3 The Company acknowledges that the representations, warranties, undertakings and indemnities contained in this Agreement are given to Nomura in connection with Admission and the Rights Issue in each case whether in its capacity as
underwriter, 

  









 financial adviser or sponsor and references in this Agreement to Nomura shall be construed accordingly. 
  
 14.4 Notwithstanding that Nomura may act as the Company’s agent in connection with the
Rights Issue, Nomura and its agents may: 
  

	(a)	receive and keep for its or the relevant agent’s own benefit any commissions, fees, brokerage or other benefits paid to or received by them in connection with the Rights Issue,
and shall not be liable to account to the Company for any such commissions, fees, brokerage or other benefits; and 

  

	(b)	keep or deal in any New Shares for which any of them may subscribe for Nomura or the relevant agent’s own use and benefit. 

  

	15.	RECEIVING AGENT 

  
 The Company confirms that it has instructed the Receiving Agent to act as receiving agent in connection with the Rights Issue and the EGM and as CREST Registrar in
relation to the Nil Paid Rights and the Fully Paid Rights and to perform the obligations assigned to it under the Circular, the Form of Proxy, the Provisional Allotment Letters and this Agreement as receiving agent. 
  

	16.	TIME OF THE ESSENCE 

  
 Any time, date or period mentioned in this Agreement may be extended by mutual agreement between the Company and Nomura but as regards any
time, date or period originally fixed, or any time, date or period so extended, time shall be of the essence. 
  

	17.	WAIVER 

  
 17.1 Any right or remedy of Nomura under this Agreement shall only be waived or varied by an express waiver or variation in writing. 
  
 17.2 No failure or delay by Nomura in exercising any right or remedy under this Agreement
shall impair such right or remedy or operate or be construed as a waiver or variation of the right or remedy or preclude its exercise at any subsequent time. No single or partial exercise of any such right or remedy shall preclude any other or
further exercise of such right or remedy or the exercise of any other right or remedy. The rights, powers and remedies of Nomura provided in this Agreement are cumulative and not exclusive of any rights, powers and remedies provided by law.

  

	18.	THIRD PARTY RIGHTS 

  
 18.1 Each Indemnified Person shall have the right under the Contracts (Rights of Third Parties) Act 1999 to enforce its rights against the Company under Clause 12
provided that Nomura (without obligation) will have the sole conduct of any action to enforce such rights on behalf of the relevant Indemnified Person. 
  
 18.2 Except as provided in Clause 18.1, a person who is not a party to this Agreement has no rights under the Contracts (Rights of Third Parties) Act 1999 to 

  









 
enforce any term of this Agreement. Nomura and the Company may agree to terminate this Agreement or vary any of its terms without the consent of any
